ZHHIMG® Granite Angle Base/Square

The structural integrity of any high-speed, high-precision machine depends entirely on its base material. ZHHIMG® utilizes its exclusive ZHHIMG® Black Granite, which provides superior physical performance compared to conventional black granites, and is vastly superior to marble—a practice we actively reject.

●   Exceptional Density (3100 kg/m³): With a density of approximately 3100 kg/m³ (3.1 g/cm³), our granite offers maximum mass and rigidity, ensuring excellent vibrational dampening and minimizing dynamic deflection during high-speed operation.
●   Static and Dynamic Rigidity: The inherent stiffness is crucial for maintaining the precise geometric relationships (flatness, squareness, straightness) required by high-acceleration XY stages and linear motors.
●   Thermal Inertia: The low thermal expansion ensures the component maintains its dimensional stability even within a temperature-controlled environment, a necessity for semiconductor processing and femtosecond laser applications.

ZHHIMG® Authority: The Standard of Structure

We do not just meet standards—we embody them. ZHHIMG®$ is the only manufacturer in this industry to hold concurrent ISO 9001, ISO 45001, ISO 14001, and CE certifications, providing unmatched assurance in quality, environmental stewardship, and manufacturing consistency.

Craftsmanship and Metrology

Our components bridge the gap between material science and absolute accuracy:

●   Manufacturing Prowess: Our advanced manufacturing capabilities allow us to process single components up to 100 tons and 20m in length. The sheer scale of our operations makes us the world's leading producer of precision granite tonnage.
●   Master Lapping: Following rough machining, the critical working surfaces are finished by our team of grinding masters, many of whom have over 30 years of manual lapping experience. This human element ensures the perpendicularity and flatness are brought to the nanometer level, far surpassing what automated systems alone can achieve.
●   Unrivaled Inspection: Every component is verified in our 10,000 m² temperature and humidity-controlled chamber (engineered with 1000mm ultra-hard concrete floors and anti-vibration trenches), using world-class instruments like Renishaw Laser Interferometers and WYLER Electronic Levels, with full traceability to national metrology institutes.
